Klebsiella is a type of bacteria commonly found in the environment, including soil and water, as well as in the intestines of humans and animals. It is a part of the normal gut flora but can become harmful when it enters other parts of the body. Infections caused by Klebsiella can lead to serious health issues, such as pneumonia, bloodstream infections, and urinary tract infections. These bacteria are known for their ability to develop resistance to antibiotics, making treatment more challenging. Proper hygiene and infection control measures are essential to prevent the spread of Klebsiella infections.
